The structure of the high-pressure steel wire wound hose is mainly composed of an inner rubber layer, a middle rubber layer, four or more alternately wound steel wire reinforcement layers and an outer rubber layer.

　　The inner rubber layer has the function of making the conveying medium bear pressure and protecting the steel wire from corrosion. The outer rubber layer protects the steel wire from damage. The steel wire (ф0.3-2.0 reinforcement layer) layer is a framework material for reinforcement.

High-pressure steel wire wound tubing (high-pressure tubing) Purpose: High-pressure steel wire reinforced hydraulic tubing is mainly used for mine hydraulic supports and oil field development. It is suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, and various Machine tools and mechanized and automated hydraulic systems in various industrial sectors transport petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) and water-based liquids (such as emulsions, Oil-water emulsion, water, etc. and liquid transmission, the highest working pressure can reach 70-120Mpa.
